Summary
The Two-Spurs wire is the most effective torquing auxiliary for Tip-Edge orthodontic treatment, efficiently controlling root movement of upper incisors. Other auxiliaries showed varied, generally lesser, efficiency in this typodont study.
Area of Science:
- Orthodontics
- Biomaterials Science
Background:
- Tip-Edge treatment is a common orthodontic technique.
- Controlling incisor torque is crucial for successful treatment outcomes.
- Various torquing auxiliaries exist, but their comparative efficiency is not fully established.
Purpose of the Study:
- To compare the efficiency of five different torquing auxiliaries in controlling upper incisor root movement during simulated Tip-Edge treatment.
- To determine the most effective auxiliary for achieving palatal root torque of the upper central incisors.
Main Methods:
- Experimental typodont study simulating the third stage of Tip-Edge treatment.
- Laser reflection method used to assess the effect of five torquing auxiliaries: Two-Spurs 0.016", Four-Spurs 0.016", Reciprocal Lateral Torque 0.016", Torque Bar 0.022x0.018" (20°), and Torque Bar 0.022x0.018" (30°).
Main Results:
- The Two-Spurs wire was the most efficient auxiliary, demonstrating good torque effect on central incisors.
- The Four-Spurs wire was less efficient than the Two-Spurs wire.
- The Reciprocal Lateral Torque wire showed good palatal root torque on central incisors and labial root torque on lateral incisors.
- Torque Bars (20° and 30°) were the least efficient, producing minimal torque effects.
Conclusions:
- The Two-Spurs torquing auxiliary is the most effective option for achieving efficient palatal root torque of upper central incisors in clinical Tip-Edge treatment.
- Choice of auxiliary significantly impacts the efficiency and speed of incisor root movement.
